16进制

这道题挺好的 学到的知识 sprintf()构成的sql注入漏洞 题目环境今天做的时候坏了 留下这几篇博客学习 https://blog.csdn.net/nzjdsds/article/details/82156123 //这篇强力推荐 https://www.cnblogs.com/wosun/p/11462305.html https://blog.csdn.net/WQ_BCJ/article/details/85215662 另一道sqli 学到的知识 注意注入点可以改成 16进制 再phone处 16进制就事hex值 来源： https://www.cnblogs.com/tlbjiayou/p/11939204.html
